6 Claims. (Cl. 126-273) This invention relates to ovens for stoves andmay constitute an improvement in portable ovens as well as in ovens thatmean integral part of stoves.

Certain foods are very satisfactorily prepared by baking, butwhere onlya single small utensil is required, a cook may hesitate to heat anentire oven for the sake of baking so small a quantity of food. If itwere possible to limit the heat to 1Q the portion of the oven reallyneeded, an oven "would be used more frequently.

The primary object of the present invention is to provide partitionswhich may be adjusted within an oven to form an enclosure which may beheated independently, of less than the full size of the oven. A furtherobject is to provide heating means arranged to heat only a portion of anoven. Other objects include the provision of simple, economical, andefficient means for retaining the various parts in both their operativeand their inoperative positions. I p the description proceeds, it willbe evident that the invention is not limited to the exact details ofconstruction of thespecificelements chosen for illustration as apreferred embodiment of the invention for the purposes stated, but manychanges, substitutions, and. modifications may be made by one familiarwith the art without departing from the principles of the invention asclaimed.

In the drawing, which shows a typical form of oven adapted for use as apermanent part of a 7 gas range, Figure 1 is a perspective view shownwith the door as opened and with portions of the walls broken away toreveal parts otherwise conceale'd; Fig. 2 is a perspective view of theoven as seen from one side of the bottom; and Fig. 315 a fragmentaryside elevation of the smallest partition, showing in solid lines theposition it occupies when not in use, and indicating by broken lines theposition it occupies when brought into active service.

The oven is shown as having a floor 1, a top 2, a back 3, side walls 4and 5. and a door 6, all of which may be of any well known or suitableconstruction. Mounted within the upper portion of the oven is a shaft '7having secured thereto, near its ends, cords or cables 8 and 9 whichhave their other ends attached to a horizontal partition 10 near itsfront edge, and cables 11 and 12 which extend from the shaft 7 overpulleys l3 and 14 to the same partition near its rear edge. A crank 15on the outer end of the shaft 7 serves as a means for rotating the shaftto wind the ends of 55 the cables thereon to lift the partition 10 fromthe position shown in solid lines in Fig. 1 to the upper position shownin broken lines in the same figure.

' A transverse partition 16, hinged at its upper edge to the under sideof the horizontal partition 80 10, may be held, when not in use,horizontally as. indicated by broken lines in Fig. 1, or may be placedvertically as shown in solid lines, with its lower edge in contact withthe floor 1. V

A partition 1'? mounted at right angles to the door 6, is also shown ashinged to the lower side ofthe partition 10 to lie parallel thereto when.not in use, as indicated by broken lines in Fig. 1

or in solid lines in Fig. 3. When in use, it hangs vertically asindicated by solid'lines in Fig. 1 and by broken lines in Fig. 3.

In Fig. 2, the gas burner 18, controlled by valve 19, is shown asextending across the rear 'half portion .of the oven, beneath thefloor 1. The burner 20, controlled by the valve 21, lies beneath theright hand portion of the front half of the oven and the burner 22,controlledby valve 23, lies beneath the left hand portion of the fronthalf of the oven.

It will be seen that with the partition 10 lifted to the upper or brokenline position of Fig. 1 and with the partitions 16 and 1'7 foldedparallel thereto and latched to hold them securely in place, the entireoven is available for usesubstantially as if the movable partitions werenot there. All of the burners, 18, 20, and 22 may be used together, orany combination found suitable.

With the partition 10 lowered to the full line position of Fig. l, butwith the partitions 16 and 1'1 still folded horizontally, the lower halfof the oven will be available for use with all or some of the burners.

When the partition 10 is in its lowered position, the partition 16 maybe swung downward and forward to shut off the rear half of the ovenportion below the partition 10. This partition 16 extends from one sidewall to the other to make a complete closure between them, as it alsoformsa complete closure between the 'partition lama the floor 1. Theburner 18 need not be used with this adjustment, since it would heatonly the space behind the partition 16, but instead, the two burners, 20and 22, beneath the front portion of the floor will heat the frontquarter of the oven between the partition 16 and the door 6 and beneaththe partition 10.

If a still smaller space is enough for some special dish, the partition1'7 'may be lowered as indicated by the arrow in Fig.3 to divide the 11front quarter of the oven described above into two separated spaces,either or both of which may be heated at will by the use of the burneror burners necessary. The temperatures may be made different in the twochambers by proper regulation of the controlling valves, and it isevident that much less gas will be needed to maintain a giventemperature in either of these eighth volume spaces than wouldberequired for the whole oven.

The partition 17 is shown as having two walls, 24 and 25, to furnish apassage for heated air from the space beneath the floor heated by theburner 22. The floor 1 has an opening closed by a small door 26 hingedto swing upward. A rock arm 27 operated by a lever handle 28 may be usedto lift the door 26 out of the opening in the floor, and when thepartition 17 is swung down.

into place, the door 26 may rest against the side of the partition asshown in Fig. l.

; The partition-17 is providedwith upper and lower air vents 29 and 30to aid in the. circulation of heatedair around the smaller chamber at.the left of which itforms a wall,. corresponding openings 31 beingformed in the inner panels 32 of the main side walls of the oven.

A It will be understood that the partitions may be made of any suitablematerial ,or layers of materials and that the showing herein is merelydiagrammatic. The art of heat insulation is well developed and it is notdeemed necessary to illustrate any specific form since obviously anydesired construction may be used which will not prevent the operation ofthe movable partitions. The latches 33 indicated as or a simple springlatch type may be replaced by any suitable means for holding thepartitions in inoperative position. i It is also to be understood thatany other suitable source of heat may be used inplace of the gas burnersillustrated, the details of COI'lStIlICf tion herein shown beingselected as merely a typical grouping of parts suitable for theaccomplishment of the purposes oi the invention as claimed.
